Have Cat Questions? Ask a Cat Vet Online.
Hi. Welcome to Just Answer. My name is***** Thank you for your question. I'm sorry to hear about Gigi's situation. The megacolon situations are ones that can be managed in a lot of cases with appropriate oral laxatives. The use of the laxation itself may not be enough for her. Using an additional laxative like lactulose or miralax can help to soften the stools to keep them passing. In her situation, is she not passing stools in the past 4 days as fecal material is building up - getting more formed as it was diarrhea prior to that? Could she be getting constipated again? Honestly, the best thing to do is to have your vet recheck her so they can know if she needs an adjustment in her treatment. If she's constipated, she isn't going to get better with just the Laxation.
Sorry about that auto correct with the "Laxation" meant to say Laxatone. HERe is a great link on megacolon and constipation.
